6:45pm: A. Sherrod Blakely of CSNNE.com tweets that the decision to waive Joseph and Varnardo may have opened the door to what could be a blockbuster deal, according to a league source. One name that has repeatedly been mentioned in speculative trade talk has been Kings' center DeMarcus Cousins (Twitter link).

5:10pm: While rounding up today's list of waived players, ESPN's Marc Stein also tweeted that forward Kris Joseph and center Jarvis Varnado had both been waived by the Celtics today.

The 6'7 Joseph had been selected by Boston as the 51st pick of the 2012 NBA Draft, appearing in six games this season and averaging 1.2 PPG in 4.0 MPG. Varnado had only played in five games, averaging 1.2 PPG in 3.6 MPG.

With the roster now at 13, ESPN Boston's Chris Forsberg speculates that the Celtics could target a veteran big man and a backup ball-handling guard to fill the two newly created roster spots. Forsberg also mentions that those potential moves could depend on the big man's asking price.
